What Our Customers Have To Say

Specialty Insulation NW re-insulated the crawl space under our house…The crawl space was wet, moldy and full of rodents. The guys came out and finished the job so fast!…They insulated our duct work and I feel so much better about what we have going on under our house.

Anisa Parks, Facebook

This company is top notch. They helped me with attic insulation, rodent proofing and a moisture barrier for my home. I had a great experience with Speciality Insulation because the owner was on site and very professional. I highly recommend this company to all.

Dr. Ben Baker, Superpages

They were very professional and honest. Let me know that things were actually in good shape, and that it didn't really make much sense for me to spend money to try to improve what I had. I appreciate that kind of honesty... I will call them back next time.

Erik C., Seattle

Did a great job...identified potential rodent access points...He made an aggressive bid for the work and delivered on everything...great service after the install - he's been back to our house twice since the work was done to make sure the crawlspace is still sealed.

Barry Rakowski

We had multiple bids...Jimmy was easily the friendliest and most professional of the bunch. It didn't hurt that his price was also the best. His installers...were courteous, clean and quite professional. No complaints at all, happy I found you guys!

Eric Shew, Google

This company is great! I had a great experience with them and have also referred them to a couple of my friends and have heard nothing but compliments about the quality of service they provide. Thanks for all your service Jimmy!

Ben B., Kirkland

Jimmie is very knowledgeable and goes above and beyond for his customers. He added attic insulation in my home, was very professional and reasonably priced. You can tell Jimmie cares about his customers and wants them to be happy.

Taylor C., Everett

Very professional. Left my house clean. Competitively priced. New attic insulation in my older home has made a significant difference in heating AND cooling costs. Thank you!
